Lock cylinder for a Pella sliding glass door

A handy person from Georgia says:
I need help identifying which would be the best lock cylinder for a Pella sliding glass door. The door currently just has a small circular blank off plate on the outside, and it is unlockable only from the inside.

Thanks for posting. Before I can offer a solution, can I see a few photos of your current handle set? That will help us find a good key cylinder for you.
A quick learner says:
It is this style: inside lever sits between inside handle and door frame. The outside handle has a circular indentation, I presume to assistance in drilling out or punching out the metal.

You could possibly use our 82-310 , but it will require either punching or drilling a hole in the outside handle. Try to knock out the hole first, but if you are not successful then you will need to drill.
A professional from CA says:
Breaking the punch out is rarely good enough.
A 5/8" drill makes a nice hole.
